Problems solved by technology

[0015] The purpose of the present invention is to provide a method for determining analog circuit experimental equipment and its required electronic components, so as to solve the problem of existing analog circuit course experimental teaching equipment with fixed circuit structure, poor expansibility of experimental content, and the establishment of comprehensive design experiments for analog circuits. The ability of the project is insufficient, which is not conducive to cultivating students' innovative thinking and the ability to apply analog circuits to engineering practice. It cannot be used alone, and it needs signal sources, oscilloscopes, DC power supplies and other equipment to carry out experiments and other defects.

Abstract

The invention provides analog circuit experimental equipment and a method of determining required electronic components thereof. The equipment includes a jumper module, an experimental electronic component plug-in module, a programmable sine signal generator, a programmable power supply, and a numerical control acquisition module; the jumper module consists of multiple row conductors, multiple column conductors and multiple jumper switches; the multiple jumper switches are arranged in a matrix mode, a first pin of the jumper switches in each row of the matrix is connected with one row conductor, a second pin of the jumper switches in each row of the matrix is connected to one column conductor, and when all jumper switches are in a disconnected state, each row of conductors and each columnof conductors are in a mutually insulated non-conductive state; the row conductors and the column conductors are connected with the pins of the experimental electronic component plug-in module correspondingly one to one. According to the analog circuit experimental equipment, the jumper module is applied to solve the problems that the wiring of a universal circuit board is difficult and error-prone and a device can be mistakenly burned.

Description

technical field [0001] The invention relates to the technical field of teaching experiment equipment, in particular to an analog circuit experiment equipment and a method for determining types and quantities of required electronic components. Background technique [0002] As a basic core course of electronics major, analog circuit has strong theory and practice, and plays a very important role in the course system. Because there are many types of devices in analog circuits, and there are infinitely many continuous states of parameters and signals, the theoretical knowledge is complex. Compared with digital circuits, analog circuits are more difficult to learn, and it is difficult to achieve an organic combination of theory and practice. It is of great significance to develop effective analog circuit experimental equipment, promote the combination of theory and practice for students, and help students apply the theoretical knowledge of analog circuits to engineering practice....
